Calculator Online – Calculate Anything Easily
Introduction
In today’s fast-paced world, having quick access to a calculator online has become essential. Whether you are a student solving math problems, a professional handling finances, or just someone trying to split a restaurant bill, an online calculator makes life easier.

Formula / Working
A calculator works on the principle of mathematical operations. Depending on the type of calculation, it uses different formulas:
- Addition:
a+b=ca + b = ca+b=c
- Subtraction:
a−b=ca – b = ca−b=c
- Multiplication:
a×b=ca \times b = ca×b=c
- Division:
a÷b=ca \div b = ca÷b=c
Advanced calculators may also include formulas for percentages, square roots, exponents, financial equations (ROI, EMI), and even trigonometric functions.

Using a calculator online is simple:
- Open the calculator tool on your browser.
- Enter the numbers you want to calculate.
- Choose the mathematical operation (add, subtract, multiply, divide, etc.).
- Click “Calculate” or press the = button.
